THOMPSON FIRST VICE PRESIDENT EAST LIVERPOOL, OHIO RICHARD B. SMITH SECOND VICE PRESIDENT EAST LIVERPOOL, OHIO JOHN M. PINNEY THIRD VICE PRESIDENT EAST LIVERPOOL, OHIO ROBERT A. WEINHARDT ASSOCIATE VICE PRESIDENT EAST LIVERPOOL. OHIO EXECUTIVE COMMITTEE J. M. WELLS CHAIRMAN M. W. THOMPSON J. H. KELLER DAVID G. BOYCE E. S. MORSE F. C. HENDERSON JOHN GEORGE Dr. Robert A. Kehoe University of Cincinnati Kettering Laboratory Eden Avenue Cincinnati, Ohio Dear Dr. Kehoe: I am enclosing a copy of the Indian Standard Specification for Earthenware Dinnerware. * You will note section 3.2.3 and 3.4 on page four refers to lead solubility and allowable limits. On page 5 sections 5.2.3 and 5.3.3 explain the sampling with the procedure shown on page 6 and 7, Appendix B. I thought you might be interested in having this information. It is surprising to me that a country not commonly considered to be very progressive has an established limit on lead solubility while the old mother hen (England) still has no established limits. It looks like the chick is getting a bit more up to date after leaving the brood. Our committee is proposing to Dr. John Koenig of Rutgers University that he run comparative tests on the same glaze between the Indian method and our A.S-T.M.tentative standard method using the dithizone test to determine the concentration in both cases. I would also like to report that our joint investigation with Lead Industries Association at Rutgers University is progressing nicely and has been extended into a 3 year effort from the 2 year effort originally proposed. We feel we are going to have a great deal of worth-while information available at the conclusion of this investigation. V 2- - Dr. Robert A. Kehoe 7/7/66 The wheels have started in motion to move the dithizone method from an A.S.T.M. tentative to a full standard. This was decided in an A.S.T.M. committee meeting at the Ceramic Convention in Washington, D. C. the first part of May, 1966. As a consequence, I feel we are making progress even though we seem to be moving at a snail's pace. I hope I have not bored you with this rather disjointed report and trust you are enjoying good health and your retirement. Yours very truly BWM/V Enc. B. W, Merwin, Chairman Research Committee Re 0020932
